When the simple—though sublime—statement is made by a man or woman that "The Lord is my Shepherd," it immediately implies a profound yet practical working relationship between a human being and his Maker. It links a lump of common clay to divine destiny—it means a mere mortal becomes the cherished object of divine diligence. This thought alone should stir my spirit, quicken my own sense of awareness, and lend enormous dignity to myself as an individual. To think that God in Christ is deeply concerned about me as a particular person immediately gives great purpose and enormous meaning to my short sojourn on this planet.
